The Open Asset Import library, or ASSIMP in short, is a C++ library which loads game-relevant 3D scene data from various file formats and returns it in a common in-memory structure. The library also offers several post processing steps commonly used in realtime 3D rendering which can be applied to the imported data. Assimp supports the following file formats: .3ds, .ase, .obj, .ms3d, .ply, .dxf, .nff, .lwo, .smd, .vta, .mdl, .md2, .md3, .md5, .mdc, .mdr, .x, .mdl, .hmp.
